The value of x for the expression -4x - 5 + 2x = -11 is 3.
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
-4x - 5 + 2x = -11 is an equation.
We have,
-4x - 5 + 2x = -11
Combine like terms.
-2x - 5 = -11
Add 5 on both sides.
-2x = -11 + 5
-2x = -6
Divide both sides by -2.
x = 3
Thus,
The value of x is 3.

Answer:
x = 3
Step-by-step explanation:
-4x - 5 + 2x = -11
add 5 to both sides and cancel the -5 on the left
-4x + 2x = -6
combine -4x and 2x
-2x = -6
divide both sides by -2 and cancel the -2 on the left
x = 3
Answer:
slope of the line perpendicular to MN = 2/3
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
the given co-ordinates are:
x1, y1 = -3, 4
x2, y2 = 5, -8
slope = -8 - 4 / 5 + 3
= -12/8
= -3/2
slope of the line perpendicular to MN = -1 / slope
= -1 / -3/2
= -1 * -2/3 = 2/3
Answer:
m = 2/3
Step-by-step explanation:
Slope = (y-y)/(x-x)
(-8-4)/5- -3) = -12/8
-12/8 = -3/2
Slope od the perpendicular line= 2/3
